A student city (70,000 students out of 220,000 inhabitants), Rennes combines an intact medieval centre, a flourishing tech ecosystem (b-com, Orange Labs) and a festive Breton spirit. Just 1h25 by TGV (high-speed train) from Paris, it's the ideal gateway to Brittany and its getaways to Mont Saint-Michel or the Emerald Coast.
Reconnect your teams for a half-day or a full day, with activities designed to unite, surprise and create shared memories, indoors and outdoors.
Our hosts travel to your premises, to a partner venue or right in the heart of Rennes, and adapt each activity to your number of participants and your objective (onboarding, cohesion, celebration).
As a team building agency in Rennes, we start with your objective rather than a catalogue. A treasure hunt in the historic centre, a blind test, a wine tasting workshop, corporate olympics: each team activity is chosen for what it produces, not for its headline effect.
As an organiser of team building, we take care of everything: design, venue, logistics, corporate entertainment on the day. The same project manager oversees your seminar and your corporate party. We operate throughout the Rennes metropolitan area and more broadly in Brittany.

More than 850 events a year. What we have learnt: the client should feel no logistical effort at all. Our process is built for exactly that.
You tell us about your teams, your goal, your date and your budget. We genuinely listen: no 40-field form.
2 to 3 reasoned scenarios: venue, activity, logistics, itemised budget. You choose, we fine-tune, we launch.
Our crew is on site. You arrive as a participant, not as the organiser. As an option, the aftermovie is delivered at D+7.
Tell us your group size, your date and what you want your team to get out of the day: your Event Expert sends you a costed proposal within 24 hours. Free, with no commitment. Prices in euros, excl. VAT.
Indicative pricing · the final price depends on the venue, the season and the options you choose
